EGFR-targeted drugs

2. EGFR-targeted drugs are mainly small molecule inhibitors.

Molecular targeting drugs developed for EGFR are divided into two major categories:

1) There are 18 monoclonal antibodies, such as cetuximab and panitumumab. They can bind to EGFR extracellular region and block ligand-dependent EGFR activation.

2) There are 68 small molecule inhibitors, including small molecule multi-target receptor tyrosine kinase (RTKs) Inhibitors and small molecule tyrosine kinase inhibitors (EGFR-TKls), which can inhibit tyrosine kinase’s activity in EGFR intracellular region.

Small molecule inhibitors

3. 9 EGFR small molecule inhibitor drugs are approved.

1) AstraZeneca has 3 approved drugs, occupying one third of the global market.

2) The approved EGFR small molecule inhibitors are mainly sued for the treatment of non-small cell lung cancer.

2) Eli Lilly has 2 approved drugs, dominating the EGFR monoclonal antibody market.

3) Cetuximab is the champion of the year, with sales twice as much as panitumumab of the same indication.
